81 Spring contact blank US3735079D 1971-04-29 US3735079A 1973-05-22 DIETERICH F
A contact strip blank of plural spring contacts from which individual spring contacts are severable. The blank has a plurality of side-by-side wire fingers joined at one end by a conductive, plated strip with the opposite finger ends extending in flexure relation therefrom. The free ends of the wire fingers are formed as radiused points of contact, and the blank is heat treated to develop hardness, wear resistance and spring characteristics in the fingers, and spring contacts of varying widths are severable from the blank by cuts in the direction of the fingers. In a preferred method, the blank is made by winding a substantial length coil of a single layer of fine, heattreatable precious metal alloy wire on a generally cylindrical mandrel, masking spaced strips longitudinally of the wire coil, silver plating the wire coil between the masked strips, removing the strips and cutting the strip-plated wire band from the mandrel as a sheet, cutting the wire sheet in the middle of the plated and unplated strips to provide the strip blanks for the forming and heat treating steps.

In a folded armature assembly the vibratory end portion of the armature is prelocatable both translationally and rotationally relative to the facing pole surfaces of the permanent magnetic flux means before attachment of the supported portion of the armature to said means. The armature has wings extending laterally from the supported portion to form therewith a connecting bridge portion, and the wings are formed to provide pads extending normal to the bridge. A magnet strap with attached magnets fits slidably between the pads, with a clearance from the bridge of the armature, to permit said locations before the parts are permanently attached. After attachment and with the magnets magnetized, the armature may be adjusted substantially in translation to magnetic center between the pole faces by appropriate plastic deformation of the bridge. In a preferred embodiment, an improved structure is provided for viscoelastic damping of the undesirable second natural resonant mode of the folded armature.

A single or double relay is provided. The relay has a base and a coil body. Each relay has a coil with an axis parallel to the bottom side of the base, an angled yoke and a plate-shaped armature. The armature is connected to a contact spring that is split into two fork-like legs. A contact leg carries a movable contact and a terminal leg that is connected to a spring carrier in the region in front of the movable armature end. With the double relay, the two armatures lie parallel at opposite ends of the base. The design yields a simple assembly with good heat dissipation particularly for a double relay for high switching currents.

A manufacturing method for an electromagnetic relay whereby a base block 20 is monolithically molded to terminals 21-24 and connector tabs 62 provided in a lead frame 60. After separating the terminals 21-24 from the lead frame 60 and bending the terminals, a permanent magnet 30 and armature block 40 are assembled into the base block 20. A case 50 is then pressed down over the base block 20 to separate the base block 20 from the connector tabs 62 of the lead frame 60. Electrical inspection and aging treatment can thus be accomplished with the base block 20 connected to the lead frame 60, improving assembly precision and productivity.
96 Electromagnetic relay and method of adjustment of a response voltage thereof US754112 1996-11-22 US5864268A 1999-01-26 Wolfgang Hoffmann; Andre Koerner; Maik Zimmer
An electromagnetic relay constructed as a hinged-armature relay in which an armature (5) is attached to a flat-shaped spring (6) which spring is constructed as one piece to serve both as a switch-contact spring and as a return spring and which is mechanically and electrically coupled to a load-current terminal (11), with the load-current terminal having a spring affixing area (11a) and a terminal area (11b), wherein the spring affixing area and the terminal area of the load-current terminal are bendable relative to one another. A response voltage of such a relay can be adjusted in a particularly uncomplicated and quick manner using a wedge-shaped adjusting tool (12) to bend the affixing area relative to the terminal area.
97 Polarized electromagnetic relay US512009 1995-08-07 US5805039A 1998-09-08 Daniel Robert Smith
A polarized electromagnetic relay includes a base, an electromagnet with a coil and a pair of pole pieces extending perpendicularly from the end of said coil, a balanced armature and spring system which when actuated pivots between two fixed contact points and a permanent magnet inducing the same magnetic poles in both of said pole pieces and providing an opposite pole in closely adjacent relationship to the central portion of the armature. A movable contact spring is fixedly connected to the armature, said spring forming contact arms at either armature end portion. Further, a flexible movable braid connects the movable contacts on said movable spring to each other and to a movable contact terminal. A pair of retaining tabs extending from a central bobbin flange engaging corresponding recesses at the lateral sides of the armature limits the movement of the armature in two directions as well as its rotation. This feature eliminates the need for a torsion spring and allows the contact forces to be higher if necessary. Two identical coils wound in a common direction are provided as the means for actuation. Armature transfer will occur by either applying a voltage pulse across the appropriate coil, or by toggling the voltage pulse polarity across the two coils connected in series.
98 Electrical switch having a stationary contact of a bimetallic material US423350 1995-04-18 US5712611A 1998-01-27 Anton Mattes; Roland Neitzel
The invention relates to an electrical switch having a contact system which includes a switching contact and at least one stationary contact. The stationary contact has a body and a contact surface which interacts with the switching contact. Furthermore, the stationary contact is arranged on a contact support which has a first wide side and a second narrow side approximately at right angles thereto and in which a recess is located in the first side, which recess has an opening, which faces the switching contact, on the second side. The body of the stationary contact is inserted into the recess in such a manner that the contact surface of the stationary contact is located on the second side. The stationary contact is designed as a bimetallic contact made of a first material for the body and of a second material in the form of a contact facing on the body. The bimetallic contact is arranged as a prefabricated part, with the contact facing as the contact surface on the contact support. A method for producing such a switch is furthermore described.
99 Polarized electromagnetic relay US525674 1995-09-25 US5617066A 1997-04-01 Michael Dittmann; Heinz Stadler; Herbert Mitschik
The relay has a base (1) with stationary mating contact elements (11, 12, 13, 14), a coil (5), a permanent magnet (4) and also a rocker armature (3) which is arranged between the coil and the base, is connected to movable contact elements (21, 22, 23, 24) and is mounted on the base by means of bearing strips, the bearing strips simultaneously serving as electrical connections for the movable contact elements. The bearing strips (25, 26) are secured to the bearing supports (15, 16), which are designed as connection elements, of the base in planes extending at right angles to the basic plane of the base. As a result, the contact separation can be set with low tolerance even during production, and it is not dependent on tolerances of the individual parts. This structure consequently permits non-problematic, cost-effective production of the individual parts and accurate assembly without the requirement of subsequent adjustment.

A thermal setting process of the bimetal strip consists in securing an adjusting pin to the trip bar by means of laser welding when the bimetal strip reaches a first preset temperature, and then checking tripping at a second temperature with or without action on a positioning screw of the bar.
